SPINDLE APPARATUS FOR CAP SEINNING .AND LIKE FRAMES.

Application filed April 16, 1923. Serial No. 632,408.

To crZZ eli/om t may concern.'

Be it known that Ij lVALTnR DARGUE, a subject of King George V of Great Britain, residing` aty Halifax, in the county ot York. England, have invented a new and useful Improvement in Spindle Apparatus ior Cap Spinning and like Frames, ot which the following' is a. specification.

My invention relates to cap spinning and like trames in which a driven bobbin is moved vertically upon a dead spindle.

The object of the invention is to provide an improved spindle apparatus for a traine ot' this type, which will overcome certain objections appertaining to the present constructions and which provide a regulated and automatic supply of lubricant to the parts which require it.

The invention will be fully described wit-h the aid ot' the accompanying drawings in which- Fig. l is a front view of one form ot spindle apparatus embodying` the invention, two spindles being shown in section and elevation respectively with the lifter plate at the bottom of its traverse.

Fig. 2 is a side elevation of a spindle, theJ lifter plate being in this instance shown at the top ot its traverse.

According to my invention in the embodiment illustrated at Figs l and 2, a fixed rail ct has bushings such as Z) to receive and support bearings such as c in which stems (Z on the undersides of wharles Z are rotatable.

The bearings c may conveniently be secured by providing them with shoulders such as. c to abut against the lower ends of the bushings Z), the upper ends of the bearings being screwed as shewn to receive internally screwed rings or collars e resting on the rail a.

The lower ends of the bearings 0 receive and form supports for the enlarged screwed ends of the fixed spindles f, and, areferably, a longitudinal fixed rail g is provided to anchor the lower ends of the spindles and hold them accurately in position. The upper ends of the spindles carry caps 7 as usual.

A vertically movable litter plate g, operated by any of the known mechanisms for the purpose, is disposed above the fixed rail a and supports bobbin hubs or driving col-- lars Zzhaving the usual driving projections Zt', to register in recesses in the bottom ends ot the bobbins e'.

Tubes or sleeves j extend upwardly from the collars Z1, to receive the bobbins7 and downwardly from said collars through openings in the lifter plate g and through the stationary wharles. The tubes j surround and are slidable upon the dead spindles f as will be understood.

The downwardly extending' portions of the tubes j have diametrically opposed longitudinal recesses or slots j, y" in which inwardly projecting tonguesI or keys Z carried by the wliarles Z engage, so that the said tubes are driven but can move vertically with the litter pflate.

The wharles Z are prevented from rising in their bearings by keeper plates secured to the rail a and engaging collars on said wharles. One plate may conveniently serve to hold down two adjacent wharles as indicated at m in Fig. l.

The stems Z of the wharles are ot ample length to term adequate supporting guides for the downwardly extending portions of the tubes 7' and the lower ends or' said stems may rest upon and be supported by antifriction rings or washers at the bottom ends or the recesses or chambers in the bearings in which said stems rotate. The upper ends ot the bearings and the screwed holding rings c may be dished to form oil wells for the reception of lubricant.

rlhe bobbin hubs or driving collars Zz preferably rest upon antifriction collars aj and said hubs may be held down by keeper plates in the same manner as th-e wharles (Z.

The bearings c are preferably formed with chambers as shewn at b2 having communication with respective external oil cups 3, so that the lower ends of the tubes y', as the lifter plate descends, will dip into said lubricant and carry same up into the bearings c and wharles rZ. The inner surfaces o't the tubes j are provided with helical grooves j2 which carry up lubricant from chamber b2 and deliver it through holes h2 at a point above the litter plate, thus lubricating automatically the washers n.

The rails a and g may be combined or united by a vertical web suitably pierced to give access to the oil cups 3.

The length ot the tube j extending through action of theA helical grooves in the inner wall of a tube, may be in excess of the quantity required for efficient lubrication.

To obviate this I may provide on the spindle, beneath the lower end of the tube, a

freely' slidable washer 0, making a good tit with. the spindle and supported by a light spiral spring p encircling the spindle, and confined between said washer and the usual enlargement f2 at the. base of the spindle. The position in which the washer 0 is normally lield by its spring, is such that as the tube descends its lower end contacts with the washer before the tube reaches its lowest position. The entrances to the helical grooves y'z are sealed or substantially sealed by suoli contact and are kept sealed during the remainder of the descent of the tube and until, as the tube ascends again, the spring p has returned the washer baclr to normal position. By suitably determining the normal position of the washer o in relation to the depth of lubricant in the well, the quantity of lubricant carried up at each descent of the tube can be regulated as desired.

Having thus described my invention I wish it to be understood that the details of construction and arrangement of the parts employed may be varied, and that I do not desire to be limited otherwise than by the scope of the appended claims, and what I claim is z# '1. In a spinning apparatus, a stationary bearing, a driving wliarl having a non-slidable tubular stem ournaled in the said bearing, a non-slidable spindle secured concentric with. the said tubular stem, a tube slidable vertically on the said spindle and in the said tubular stem, means for revolving the said tube/from the wliarl, and a bobbin operatively connected with the said tube.

i2. A spinning apparatus as set forth in claim l, the said tube being splined to the tubular stem of the wharl to permit it to be revolved and to be slid vertically. ,y

3. In combination with a spinning apparatus as set forth in claim 1, a reservoir for lubricant formed in the lower part of the stationary bearing and into which the lower end portion of the said tube is dipped at each downstrolre.

4f. In combination with a spinning apparatus as set forth in claim l, a reservoir for lubricant formed in the lower part of the stationary beai'ing and into which the lower part of the said tube is dipped at each downstroke, groove which raises the lubricant as the tube is revolved.

5. In combination with a spinning appasaid tube having an internal helicall ratus as set forth in claim l, a reservoir for f lubricant formed in the lower part of lthe stationary bearing and into which the lower part of the. said tube is dipped at each downstroke, said tube having an internal helical groove which raises the lubricant as the tube is revolved, and a spring-supported washer mounted in the said reservoir and operating to close the lower end of the said helical groove at a predetermined point of the downstrolre of the tube.

6. A spinning apparatus as set forth in claim l, the means for connecting the bobbin to the said tube comprising a driving collar secured on the tube, the said collar and bobbin having interlocking parts so that they Arevolve together, and said bobbin being removable from the tube.

7. A spinning apparatus as set forth in claim l, the said non-slidable spindle being provided at its lower part with a screw-- threaded portion of larger diameter than its main portion, said screwthreaded portion being screwed into the lower part of the said stationary bearing and securing the said spindle to it.

In testimony whereof I afliX my signa-ture.
